Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of online conductivity monitoring devices, and specifically relates to an online conductivity monitoring device for a bath liquid with an electric field. Background Technology
[0002] When electronic aluminum foil undergoes energy formation in the electrolyte of the forming tank, the concentration of the electrolyte in the reaction tank gradually decreases with production. To control the conductivity of the electrolyte within a reasonable range, electrolyte needs to be replenished regularly. The basis for replenishment is to understand the real-time conductivity value. Current technology relies on operators to periodically sample and test the liquid in the tanks of the production line. However, with a large number of tanks in the production line, sampling and analysis are time-consuming and the results are delayed. It may take a long time before the conductivity of the electrolyte in a certain tank deviates from the normal range before it is discovered. By then, it is too late to take remedial measures. If the conductivity deviation is too large and the time is long, it can easily cause product quality problems. Therefore, online conductivity monitoring devices for tank liquids with electric fields have emerged on the market. These devices are designed for environments with large electric fields, such as electronic aluminum foil forming tanks, to achieve real-time monitoring of electrolyte conductivity.
[0003] For example, Chinese patent CN202041585U discloses an online conductivity monitoring device for a tank solution with an electric field. The upper part of the outlet of the tank solution circulation pump is connected to a front solenoid valve. The outlet of the front solenoid valve is connected to the upper inlet of the measuring tube. The lower outlet of the measuring tube is connected to a rear solenoid valve. The outlet of the rear solenoid valve is connected to a discharge dispersion pipe that extends into the reaction tank. The front solenoid valve, the rear solenoid valve, and the electrode probe are connected to a time controller in the control cabinet via control lines. The electrode probe and the temperature measuring probe are connected to a conductivity meter via data lines. The conductivity meter is connected to an industrial controller via a data line. The industrial controller has a display screen.
[0004] The aforementioned patent enables online monitoring of the conductivity of the electrolyte in the tank during normal production, under conditions where the electrolyte has a large electric field. However, the device still has some shortcomings that need improvement. In the existing device, the positions of the temperature measuring probe and the electrode probe are fixed, and the height cannot be adjusted according to changes in the electrolyte level or concentration distribution in the measuring tube. The measurement data is easily distorted due to improper probe immersion depth, especially when the electrolyte level fluctuates, which affects the monitoring accuracy. Furthermore, after long-term use, impurities may adhere to the surface of the conductivity electrode, affecting the measurement accuracy. Utility Model Content
[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an online conductivity monitoring device for an electric field bath liquid, so as to solve the problems in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] An online conductivity monitoring device for an electric field bath includes a measuring tube and a reaction tube. A fixing frame is fixedly connected to one side of the measuring tube, and two fixing frames are provided. A power component is provided on one side of each of the two fixing frames.

[0008] As a preferred technical solution, the power assembly includes a motor, which is fixedly connected to the top of the fixed frame. A drive gear is fixedly connected to the output end of the motor. A driven gear is meshed with one side of the drive gear. A lead screw is fixedly connected to one side of the driven gear. The lead screw is rotatably connected inside the fixed frame. The hanger is threadedly connected to the lead screw.
[0009] As a preferred technical solution, the fixed frame has a sliding groove inside, the lead screw is rotatably connected inside the sliding groove, one side of the hanger is slidably connected inside the sliding groove, a sliding rod is fixedly connected inside the sliding groove, and one side of the hanger is slidably connected to the sliding rod.
[0010] As a preferred technical solution, the air source component includes an oil-free air compressor, which is located on one side of the measuring tube. An air storage tank is fixedly connected to the output end of the oil-free air compressor, and an air pipe is fixedly connected to the output end of the air storage tank. A shunt pipe is fixedly connected to one side of the air pipe.
[0011] As a preferred technical solution, the shunt tube is fixedly connected to the measuring tube, and a jet head is fixedly connected to the side of the shunt tube away from the air tube. Multiple jet heads are provided, and the jet heads are close to the electrode probe.

[0013] In summary, the present invention has the following main advantages:
[0014] First, this utility model, by setting up a power component, uses a motor to drive the active gear and the driven gear, causing the lead screw to rotate and drive the hanger to slide along the slide groove and the slide rod. This allows the two probes to flexibly adjust their immersion depth according to the changes in the electrolyte level or concentration distribution in the measuring tube. This avoids the distortion of measurement data caused by improper probe immersion depth. Even if the electrolyte level fluctuates, it can ensure that the probe is always in a suitable measuring position, thus improving the monitoring accuracy. Furthermore, when cleaning the electrode probe, the temperature measuring probe can be extended out of the measuring tube to avoid affecting the operation of the electrode probe.
[0015] Secondly, by setting up an air source component, the gas generated by the oil-free air compressor is delivered to multiple jet heads through an air tank, air pipe and distributor pipe. This can clean the impurities adhering to the surface of the electrode probe measuring end after long-term use, avoid the influence of impurities on the measurement accuracy, reduce measurement errors caused by cleaning problems, and reduce the frequency of manual cleaning.

[0021] Example
[0022] refer to Figures 1 to 4 The online conductivity monitoring device for an electric field bath liquid described in this embodiment includes a measuring tube 1 and a reaction tube 2. A fixing frame 5 is fixedly connected to one side of the measuring tube 1, and there are two fixing frames 5. A power assembly 6 is provided on one side of each fixing frame 5. A hanger 7 is slidably connected to one side of the fixing frame 5 through the power assembly 6. A temperature measuring probe 3 is fixedly connected to one side of one hanger 7, and an electrode probe 4 is fixedly connected to one side of the other hanger 7. A gas source assembly 8 is provided on one side of the measuring tube 1. It should be noted that a drain pipe is also fixed at the bottom of the measuring tube 1. The electric field bath liquid in the reaction tube 2 flows into the measuring tube 1 through a third pipe 11 and a first pipe 9. The two fixing frames 5 on one side of the measuring tube 1 provide installation support for the power assembly 6 and the hanger 7. The power assembly 6 drives the hanger 7 to slide, so that the temperature measuring probe 3 and the electrode probe 4 enter the bath liquid in the measuring tube 1 to detect the temperature and conductivity, respectively.
[0023] refer to Figure 4 The power assembly 6 includes a motor 61, which is fixedly connected to the top of the mounting frame 5. A drive gear 62 is fixedly connected to the output end of the motor 61. A driven gear 63 is meshed with one side of the drive gear 62, and a lead screw 64 is fixedly connected to one side of the driven gear 63. The lead screw 64 is rotatably connected inside the mounting frame 5, and the hanger 7 is threadedly connected to the lead screw 64. By setting up the power assembly 6, the motor 61 drives the drive gear 62 to rotate, which in turn drives the driven gear 63 to rotate. The driven gear 63 then drives the lead screw 64 to rotate within the mounting frame 5. Because the hanger 7 is threadedly connected to the lead screw 64, when the lead screw 64 rotates, the hanger 7 slides along the axial direction of the lead screw 64, thereby moving the temperature measuring probe 3 or the electrode probe 4 up and down, achieving probe height adjustment and effectively avoiding measurement errors caused by a fixed probe position.
[0024] refer to Figure 4 The fixed frame 5 has a sliding groove 65 inside, the lead screw 64 is rotatably connected inside the sliding groove 65, one side of the hanger 7 is slidably connected inside the sliding groove 65, and a sliding rod 66 is fixedly connected inside the sliding groove 65. One side of the hanger 7 is slidably connected to the sliding rod 66. By setting the sliding groove 65 and the sliding rod 66, when the hanger 7 slides under the drive of the lead screw 64, one side of it moves along the sliding groove 65 of the fixed frame 5. At the same time, the hanger 7 is slidably connected to the sliding rod 66. The sliding rod 66 plays an auxiliary support and guiding role for the hanger 7, restricting the hanger 7 to move only in the vertical direction and avoiding deviation during the sliding process.
[0025] refer to Figures 1-3 The air source assembly 8 includes an oil-free air compressor 81, which is located on one side of the measuring tube 1. An air tank 82 is fixedly connected to the output end of the oil-free air compressor 81, and an air pipe 83 is fixedly connected to the output end of the air tank 82. A splitter pipe 84 is fixedly connected to one side of the air pipe 83 and is fixedly connected to the measuring tube 1. Multiple nozzles 85 are fixedly connected to the side of the splitter pipe 84 away from the air pipe 83, and each nozzle 85 is located near the electrode probe 4. By configuring the air source assembly 8, the oil-free air compressor 81 produces… Compressed gas is transported to the gas storage tank 82 for storage and pressure stabilization. The gas in the gas storage tank 82 enters the distribution pipe 84 through the gas pipe 83. The distribution pipe 84 distributes the gas to multiple jet nozzles 85. The jet nozzles 85 spray gas onto the electrode probe 4. The high-speed ejected gas forms dense bubbles in the electrolyte in the measuring tube 1. As the bubbles rise, they drive the surrounding water flow to churn violently. The water flow forms a scouring force on the surface of the electrode probe 4, peeling off the impurities attached to the probe surface and carrying them away with the water flow, thus achieving efficient cleaning of the electrode probe 4. It should be noted that a solenoid valve is installed on the gas pipe 83.
[0026] refer to Figure 1The measuring tube 1 is fixedly connected to a first pipe 9 on one side, and the reaction tube 2 is fixedly connected to a third pipe 11 on the side close to the first pipe 9. The third pipe 11 is fixedly connected to the first pipe 9, and the measuring tube 1 is fixedly connected to a second pipe 10 on the side away from the first pipe 9. The tank liquid in the reaction tube 2 flows into the first pipe 9 through the third pipe 11 and then into the measuring tube 1. After the measurement is completed, the tank liquid is discharged through the second pipe 10.
[0027] Operating principle and advantages: The charged bath solution in reaction tube 2 first flows into the first pipe 9 through the third pipe 11, and then enters the measuring tube 1. Afterwards, based on the liquid level and concentration distribution of the bath solution in measuring tube 1, the power assembly 6 is activated to adjust the probe position. The motor 61 drives the drive gear 62 to rotate, which in turn drives the driven gear 63 to rotate. The driven gear 63 drives the lead screw 64 to rotate within the slide groove 65 of the fixed frame 5, causing the hanger 7, threadedly connected to the lead screw 64, to slide along the slide rod 66. This adjusts the height of the temperature measuring probe 3 and the electrode probe 4 respectively, ensuring that both probes are at the appropriate measurement depth. Subsequently, the two probes are activated... Upon startup, temperature probe 3 detects the temperature of the bath liquid, and electrode probe 4 detects the conductivity, thus completing online monitoring of the bath liquid. When electrode probe 4 needs cleaning, the temperature probe 3 is first moved out of the measuring tube 1 via power assembly 6, and the solenoid valve on air pipe 83 is opened, and air source assembly 8 starts working. Compressed gas generated by oil-free air compressor 81 is delivered to air tank 82 for storage and pressure stabilization, and then distributed to multiple jet nozzles 85 via air pipe 83 and distributor pipe 84. The jet nozzles 85 spray gas onto electrode probe 4, and the high-speed gas forms dense bubbles in the bath liquid, driving the water flow to churn and wash the surface of electrode probe 4, peeling off impurities and carrying them away with the water flow.
